DISCUSSION POINTS
- Simulations conclusions, updates, and next phase
- Shielding and magnet model CAD (Josh)
- Hall A/C model and design/implementation (Steven, Mike, Paulo)
- NPS+CPS experiments
- Other
PARTICIPANTS:
Hamlet Mkrtchyan, Igor, Mike Fowler, Sean Dobbs, Tanja Horn, Paulo Medeiros, Mike CAD, Steven Lassiter, Vardan Tadevosyan, Vladimir Berdnikov, Marie Boer, Rolf Ent, Gabriel Niculescu, Dustin Keller, Donal Day, A Comer
SUMMARY NOTES
RADIATION SIMULATIONS UPDATE (Gabriel)
- Conclusion: we are "there" - Picked configuration mk_V
- No need for pink plastic in front - keep lead there
- Air in exit channel - important to pump, since would give radiological gases
- Need gate valve and window to separate scattering chamber from beam line (simulation has entrance window)
CONCLUSIONS: BRIDGING SIMULATION AND MECHANICAL DESIGN (Rolf, Josh, Tanja)
SUMMARY OF CONCLUSIONS AND SHIELDING SKETCHES
- Listing of radiation and material for mk_V
- Seems to suggest ~50 ton device
- Sketches of shielding configuration: side view, front view (how many bricks there are and how to stack them) - start at z=+5cm and estimate total height (155cm), width (180cm) and length (~200cm)
- Hall D KLong possible configuration
- Position magnet with respect to beam - narrow beam pipe hole (3mm), so need very accurate positioning
- Perhaps change beam pipe to have tolerance on all sides
- Mainly need good beam position - need to be able to align to better than 1mm
INITIAL CAD MODEL OF MAGNET AND SHIELDING
- Magnet pole piece is angled to increase the field
- Note: no field clamp needed for CPS magnet
- Shielding model is still simplified - see action items below
- Next steps:
- Need to also take into account the assembly - which piece goes in first, plus:
- cooling, forces, services to magnet etc.
- outer containment for tungsten and poly - container to hold tungsten (stainless steel typically since it is heavy)
- Division of W-Cu insert should minimize heat transfer between segments
- Discussion of best way to interface with engineering/design team
- Autodesk Inventor - should be able to transfer files
- Action Items - to address before turning over to engineering/design team
- Cu-W inserts
- Form of W blocks - get information from vendor
- Container for W blocks
CPS IN HALL C MODEL PRESENTATION (Mike)
- Discussion of the Hall C model including the CPS
- There are interferences - need to further discuss
- Action item: make ppt slides with screen shots - DONE (see link under Discussion items)
NPS+CPS EXPERIMENTS (Marie, Dustin, Vardan)
- Ongoing simulation efforts
- Background studies with pi+/pi- generator
- Plan to run several settings to optimize signal/background
NEXT MEETING: FRIDAY 29 MAY AT 11:00AM (ET)
